A Progressing Cavity Pump is a semi-positive displacement pump consisting of a single rotor turning eccentrically in a stator having twice the pitch length of the rotor. This forms a series of spiral shaped sealed cavities that progress from suction to discharge. This allows it to maintain a constant flow with varying degrees of pressure and head conditions.
Progressing Cavity Pumps do not have a natural shutoff head or the worries of irksome floats. Instead they use a “trapped air” system. This consists of an “on/off” and “alarm” pressure switches that are tripped when the water level rises. Switches in the control panel sense the pressure to turn the pump on or off, or to activate the alarms.
Progressing Cavity Pumps do not become air bound, an anti-siphoning check valve is used to prevent air release into the pressure sewer and keep the rotor and stator lubricated.
A Stainless Steel Cutter Wheel with Bars can handle a wide range of different solids. The wheel emaciates all solid material into pieces so small they easily move through narrow pipes. It is durable and robust; it will turn anything into a fine slurry.
A 1HP, 1725 RPM, 120/240 high torque motor is used with a capacitor start-capacitor run (CSCR). Its robust torque can propel the liquid through the inflow and infiltration-free pressurized 2 to 4-inch pipe for more than 2 miles (even uphill).
An automatic reset thermal overload protection is built it. Power consumption is low making Progressing Cavity Pumps extremely affordable.
